Rails2.3 plugin install git:// problem

What am I missing here?

This doesn't work:

-*- mode: compilation; default-directory: "~/journeys/" -*-
Compilation started at Mon Mar 2 08:13:15

script/plugin install git://github.com/rubyist/aasm.git
Plugin not found: ["git://github.com/rubyist/aasm.git"]

I have had luck replacing the heading git:// with http://

Hi, if you’re wanting to install Rails 2.3, you have a couple of options:

a) As Gem

sudo gem install rails --source=http://gems.rubyonrails.org

b) Edge Rails (within a project)

rake rails:freeze:edge

Good luck,

I can access a site that advertises an http location, though I'm not
sure it's not the svn in the path that makes it work.

For instance:
